The molecular geometry of the complex of gallium trichloride with ammonia, Cl 3Ga.NH 3, has been studied by electron diffraction. The most important internuclear distances in terms of r a parameters are as follows: r(Ga-Cl) = 2.142±0.005, r(Ga-N) = 2.057±0.011, r(ClCl) = 3.642±...
A systematic investigation of the M + BF 4 (M=Li or NH 4 ) ion-pair conformers has been carried out using an electrostatic docking model based on the molecular electrostatic potential topography of the free anion. This method provides a guideline for the subsequent ab initio molecular orbital...
This correspondence between electron pair domains and valence shell charge concentrations provides a physical basis for a better understanding of the VSEPR model. Key rvords: VSEPR model, electron densities, nlolecular geometry, Laplacian of the electron density, electron pair domain. R. J . ...
What is the electron pair geometry of H_2CO? Define electron affinity. In which corner of the periodic table is the highest? Explain why this is so. What is the electron domain of phosphorous trichloride? Why is electron affinity stronger (bigger negative) for Cl rather than Fl? What ion...

Electron channelling contrast imaging (ECCI) can be used in a near normal incidence geometry [38], [39] or in a forescattered geometry where the sample is tilted from 30° to 70° toward the electron sensitive detector positioned to collect electrons scattered to low take-off angles. Electron...
Write the electron configuration of the iron atom, Fe(II) ion, and Fe(III) ion. Draw the electron configuration for each of the given metal ions assuming that they each form complexes with an octahedral geometry. State the number...
Structure C shows an interaction between Rh(I) and the nitrogen lone pair of the nitrile substituent. Values in blue color correspond to the NBO charges on Rh(I). alkyne, the more stable complexes B, observed for arenes of good and moderate donor ability, correspond to the ca...
